Batman RIP and everything after - Batman Inc etc - was all Morrison and was originally meant to be a 4-issue run. Damien's death was to conclude that run. Morrisson's whole story is supposed to be a Batman history tribute type thing. I still think it's shit. But it isn't 'DC' in that respect, demanding a death to sell more comics. As Jason Todd died, Morrison thought it necessary that his Robin should do the same.

Geoff Johns talks Superman I & II on Fatman on Batman and reveals some cool shit.
